Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

A running example of the code from:

This gist creates a working example from blog post, and a alternate example using simple worker pool.

TLDR: if you want simple and controlled concurrency use a worker pool.

:q        close
:w        write/saves
:wa[!]    write/save all windows [force]
:wq       write/save and close

Update: please note that I have since switched to using a set of bash scripts instead of poluting the Git repository with git svn.

Place me.mailcatcher.plist into ~/Library/LaunchAgents, then run launchctl load ~/Library/LaunchAgents/me.mailcatcher.plist.

~~If you use pow, echo 1080 > ~/.pow/mailcatcher and go to http://mailcatcher.dev, otherwise use http://localhost:1080.~~

Currently pow doesn't seem to pass websockets through correctly. Looking into this.
